yeah, those vimeo videos are real. the 2nd link has footage seen in the documentary found in TM Head On Extra Twisted Edition. The first link video is an unfinished cut-scene, and the subtitles/dialogue was probably edited in because no voice acting was recorded.

The 9/11 Conspiracy Theory TMB video is ridiculous though. Pretty funny coincidence that the steam on the coffee billboard resembles the number 911. The video gets David Jaffe's birthday completely wrong though, so very poor investigating. He wasn't born in April, he was born in December. After 9/11 happened Twisted Metal Black's Euro version did get extra censored, and the option to destroy the plane in the Junkyard map was taken out. Skyscrapers was left alone. Skyscrapers has some eerie coincidences for sure, but it was a map made before the 9/11 tragedy, and Jaffe definitely didn't have inside info. One look at his twitter will confirm his political ignorance, so I think it's hilarious some crazy youtube conspiracy theorist would think David was some sort of Illuminati member.
